System Programming

In the second week of this course, we'll learn about system programming. We will explore ways that IT Support Specialists might use programming skills to create automation to save time and cut down on mistakes. We'll start by looking at how we can organize code, how to read and write files, use subprocesses and input streams, and learn about code libraries and how they're packaged. By the end of this module, you will write a Ruby script to discover all the hosts on a local network.
